Volkswagen has over 1.4 billion investment in solid-state batteries

On June 17, Volkswagen announced an increase in the shareholding of Quantumscape, a Silicon Valley solid-state battery developer, and will add an additional US$200 million (approximately RMB 1.42 billion) in investment.
Compare Conventional Battery with Solid State Battery
Quantumscape was founded in 2011 and is headquartered in San Jose, California. The company has about 200 patents and patent applications related to solid-state battery technology.

Volkswagen and Quantumscape reached a cooperation in the field of solid-state battery technology as early as 2012. In 2018, Volkswagen invested 100 million US dollars to become its largest shareholder, and jointly established a joint venture company focused on solid-state battery research. It is expected to set up a pilot plant by 2020.

With this capital increase, Volkswagen aims to advance the development of solid-state batteries and plans to establish a solid-state battery mass production line by 2025.
Copper foil for lithium battery
Internationally, Samsung Technology Research Institute (SAIT) and Japan's Samsung Research Institute (SRJ) have launched next-generation solid-state battery technology that uses a silver-carbon (Ag-C) composite layer as the negative electrode.

The thickness of the copper foil material is only 5μm (micrometer), allowing the research team to reduce the thickness of the negative electrode and increase the battery energy density to 900Wh/L, which is 50% smaller than traditional lithium-ion batteries. Up to 800 kilometers of battery life on a single charge, up to 1000 cycles.
